CORNELIUS A. SHERIDAN, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF IO FRANK MCGOUGH, OF SAME PLACE.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent NO. 269,887, dated January 2, 1883.

Application filed September 5, 1882. (No model.l

f DAN, of Detroit city, county of \Vayne, State of Michigan, have invented a new and useful Improvement in Refrigerators; and Ideclare the following to be a full, clear, and exact. de-

scription of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specication.v

My invention consists in the combinations of devices and appliances hereinafter specified, and more particularli` pointed outin the claims.

In the drawings, Figure 1 is a plan view ot' an apparatus embodyingl my invention. Fig. 2 is a cross-section. Fig.3 is a side elevation with the side wall removed, showing one side with the wood lining or stay.

The object of my invention is, first, to provide a refrigerator, adapted in various sizes for stationary use or in refrigerator cars, which shall furnish the most cooling-space in theleast room second, to provide suoli a refrigerator which may be taken apart so as to be easily moved and repaired; third, to furnish in such a refrigerator means whereby it may be readily cleansed. I design to accomplish this object by constructing a refrigerator in sections properly secured together by the use of grooved or corrugated surfaces, and by providing a manhole or a handhole, as the case may be, so located that the refrigerator can readily be cleansed of impurities.

In carrying out my invention, A is the preserving chamber, constructed in any proper manner.

B is the refrigerating-chamber or ice-box. I design to construct this refrigerating-chainber in sections B and B2, each section provided with a 'metallic lining, B3, inside the walls A', said lining i'luted, grooved,or corrugated on as many sides as may be practicable. I prefer to construct each of these sections with aslanting or curved base, b, preferably lluted, also provided with a suitable gutter, b', and outlet b2. The different portions ofthe metallic lining may be secured together in any proper manner, either being riveted and soldered together, as

shown in section B', or they may be screwed or 5o bolted together 'with a rubber or other packing between, as shown in section B2, either with or without interior stays of wood, b3. Each of the sections is, furthermore, provided with a suitable cross-plate, b4, through which the two sections may be screwed or bolted together in such a manner that they may be easily taken apart. A suitable rubber orother packing may be interposed between the two cross-plates to maketheconstruction water-tight; but I prefer 6o to provide said plates with an appropriate cap,

C, to secure this result.

b5 represents braces adapted to strengthen the sides of the metallic lining B3, and also to support one ofthe lids or coversl). The whole lid may be constructedto open for the entrance of the ice; or the cover may be provided with a smaller door or trap for this'purpose, as may be desired.

E represents a drip-pan under the gutters b', 7o adapted to catch any condensed vapors which may gather under the base ofthe refrigeratiugchamber.

F represents man-holes or hand-holes, as the case may be,`oy means of which the refrigeratingehamber may be cleansed.

It is evident that by constructingthe lining of the refrigeratingchamber of uted metal a much larger' cooling-surface is obtained than it' the lining were an ordinary dat surface, while 8e at the same time the fluted surface occupies no more room. t

It is obvious, also, that by the use of tinted surfaces the refrigerating-chamber may be lo cated directly against the sides of the ret'rig- S5 erator or car, the air being free to pass down through the grooved spaces to the Ln'eserving-- chamber.

I would have it understood that I do not confine myself to a refrigerator whose refrigerat- 9c ing-chamber is constructed, in the manner described, of two sections only, as it is obvious that it might be constructed of two or more sections united as described without departing from the principle of my invention.

That I cla-im is- 1. In a refrigerator or refrigerator-car, a rei frigerating-chamber constructed in two or more sections, each section constructed with a metallic lining fluted on one or more sides, said sections adapted to be readily united and separated, substantially as described.

2. 1n a refrigerator or refrigerator car, lthe combination, with the walls of the refrigerator and a. suitable preserving-chamber, of a refrigerating-chamber adapted to receive refrigerating material, said chamber constructed of two or more sections adapted to be united und separated, each of said sections provided with a l metallic lining luted on one or more sides, the construction being such that air may pass from the refrigerating-cham ber into the preservingchamber through the grooves of the fluted lining, substantially as described.

3. A refrigerator consisting ofthe combination, with the walls of the refrigerator and a. suitable chamber, of a refrigeratirig-chamber adapted to receive refrigerating material, said chamber constructed of two or more sections, i

united as Specified, each of said sections provided with a metallic lining tluted on one or more sides, a gutter, an outlet leading therefrom, and a drip pan underneath the gutter, substantially as described.

4. In a refrigerator 'or refrigerator-car, a refrigeratilig-chamberconstructed in two or more sections adapted to be readily united and separated, and in combination therewith a suita-
